DRAFT-EQUALIZER.

Specification of Letters Patent.

, To all whom, it" may concern.-

Be it known that I, VVILLLAM L. VIEBROCK, a citizen of the United States, residing at Lime Spring, in the county of Howard and state ol' Iowa, have invented a new and useful DraitEqualizer, of which the following is a specification.

The present invention has more particular reference to means for hitching a number of draft-animals to an agricultural implement, such as a plow, though not necessarily limited in this respect.

One of the principal objects is to provide a novel structure of the above character that may be connected to a plow and will so locate the draft animals with respect thereto that all but one will be upon unplowed ground, while the one will walk in the last or open furrow. Thu none of the animals are compelled to lt'ctlli upon plowed ground, and their full strength is secured without any abnormal or undue work being placed upon one.

Another and important object is to provide means whereby the evener may be readilv adjusted with respect to the implement in oi'der that side drafts or other lateral strains may be entirely eliminated.

The 'n'cl'crrcd embodiment oi the invention is illustrated in the accompanying drawings, wherein v Figure 1 is a plan view ol' a plow with the equalizer conncctcd thereto, Fig. 1s a perspective view of said equalizer F1g. 3 is a sectional View on the line 3 3 of Fig. 1. Fig. 4 is a view, )artly in elevation and partly in section, of the holding-link.

Similar reference-1minerals designate corresponding parts in all the figures of the drawings.

- In the embodiment illustrated a wheelilow is shown, two plows being carried thereby and having sniced beams 5. The rear portion of these eams are connected by a tic-bolt 6 and a spacing device'7, interposed between the beams and carried by' the bolt. The front end of the beams are also connected by a tie-bolt 8 and are held in spaced rela tion by a sleeve 9, interposed between the beams and mounted on the bolt 8. This bolt, as clearly shown in Figs. 1 and 2, projects beyond one of the beams 5, its free end being connected to said beam by a. rearwardly-ex tending brace 10. Journaled on the projecting end of the tie-bolt 8, between the brace 10 and the adjacent beam 5, is a clcvis 11,

provided with the usual series of openings 12,

said clevis being thus horizontally disposed and being located at one side of the beams;

An evener is employed, consisting of a lever l3, fulcumcd to a rearwardly-extending yoke 14, the fulcrum being located nearer one end of the lever 13 than the other. Upon the shorter arm of the lever is pivoted a whifiletree 15, and on the ends thereof are mounted the usual doubl'etrees 16, carrying swingletrees 17. To the longer arm of the lever 13 is connected another swingletree 18. The usual tongue 19, connected to the' plowframe, extends in advance of the vehicle between the two right-hand swingletrees. It

will thus be seen that in the present fivehorse evener four of the animals will be located on unplowed ground, While the'fifth can walk'in the last smooth open or dead furrow.

The vehicle is connected to the plow by the following means: A link 20, composed of strap-sections, has its rear end embracing and pivoted nis shown at 2-1, to the clevis 11, the pivot-bolt 21 being adjustable along said clevis. pivoted by a bolt 22 to and between a set of three cars 23, formed at the rear end of the yoke 14. the link 20 is disposed in angular relation to the clcvis 1 1, and its angular relation is maintained by means of a holding-link 24, the front end of which is'in the form of'a stirrup 25, that slidably embraces the tie-bolt 8 and clevis 11 and is connected to the rear end of the yoke 14, and consequently to the front end of the link 20, by the pivot-bolt 22. This stirrup is provided with longitudinally-dis posed slots 26, through which passes a guidebolt 27, that also passes throu h one of the openings 12 of the clevis 11. '%he rear portion of the link 24 consists of rod-sections 28, having flat portions 29, overlapped and pro- 1 vided with s ots 30, through which are passed holding-bolts 31. The front section 18 swiveled, shown at 32, in the rear end of the stirrup 25, while the rear section'lias at its rear end an eye 33, that-receives'a clip 34, fastened to the outer plow-beam 5. It will thus be seen that the link 24 is extensible, that it is slidably associated with the clevis 11 and that it maintains the link 20 inaugular relation to said clevis.

With this structure, therefore, none of the; draft-animals has to travelover the 99311.0:-

The front end of the link 20 is roughplowedground, and conse uently none has to do more than its share 0 work. At the same time the connections are such that there is no side draft,-and by shortening or lengthening the link 24 not only can all latera strains of this sort be elimina' id, but the said link permits the ready attachment of the equalizer to different implements and ,furthermore, allows the link to be adjusted at any desired osition upon the clevis 11. Furthermore, 1; e animals are directly connected to both beams by the relatively movable links 20 and 2'4, the main draft being, erhaps, on the'link 20, and while the same is isposed diagonally of the" line of draft side draft therebyris preiianted by the opposite disposition of the other link 24, the action of which can 'be'vari'ed b shortening 'or extending it tothrow said Ii 20 more or less transversely of'saidline of draft. The link 24, moreover, with its connections imparts draft to the 0 posite side of the plow to that carrying tl ie whifiletrees, and its lon 'tudinal strain diagonally of the line of dra is op osed to that of the other an larly-disposed link 20. The spaced and a justable connections 21 and 27 are im ,ortant features; the same maintaining the re ative 1positions of the draft-links with respect to t e clevis, but further than this the bolt 27 revents the lateral playof the stirrup and 'nk when a turn is made to the right and is readily adjustable in changing the spaces between the beams to reg ilate the may "be resorted to w 1t ows.

From the foregoing it is thought' 'that the construction, operation, and many advantages of the herein-described inyention will be a parent to those skilled: in the art with out fil'lBI-dGSCTiptiOII, andit will be understood that various chang in the size, shape, proportion, and minor details of construction out departing from the spirit or sacrificing ny of the advantages of theinvention.

Having thus described my invention, what I claimas new, and desire to secure by Lettors Patent, i s- 1. 'The'cornb nationjwith an evener, of a substantial; horizontal clevis, means for connecting the 'clevis to an implement,-. a link connectingthe e'vener and clevis and disposed in angular relation to the line of draft, anotherli-n'k connected to the cvener and dis posedsdiagonally of the line of draft and in angular re ationito the first-mentioned link,
